A plane is seen covered in volcanic ash in San Carlos de Bariloche airport, southern Argentina, Tuesday June 7, 2011. The wind carried volcanic ash across the Andes to Argentina resulting in the closing of six airports, and the cancellation of flights in the capital city. The Puyehue volcano, dormant for decades, erupted in south-central Chile on Saturday. (AP Photo/Alfredo Leiva). Click to zoom.
